William Klesalek specializes in specialty trade contracting with a demonstrated focus on infrastructure maintenance and repair, particularly in fencing systems and perimeter security installations. The contractor delivers precise, field-ready solutions for federal facilities, leveraging hands-on expertise in material selection, structural anchoring, and corrosion-resistant assembly techniques. Their work emphasizes durability, code compliance, and minimal disruption to operational environments—key for agencies managing sensitive or rural sites. Technical proficiency includes site assessment, load-bearing framework installation, gate hardware integration, and adherence to USDA and USDA-FSIS facility standards for secure, long-lasting perimeter enclosures. The contractor has performed work exclusively for the Department of Agriculture, where projects involve the repair and restoration of fencing infrastructure on agricultural research lands, wildlife management areas, and rural federal property. This relationship suggests a niche alignment with USDA’s land management and conservation missions, particularly in maintaining secure boundaries for livestock, research plots, and protected natural resources. Work is typically mission-critical, requiring coordination with field personnel and environmental compliance protocols. The primary NAICS code 238990 reflects a broad specialty trade contracting scope, but contract performance indicates a clear vertical specialization in perimeter security and boundary infrastructure—distinct from general construction or electrical work. This positions the contractor as a targeted provider for agencies needing durable, low-visibility fencing solutions that meet federal land-use requirements. As a sole proprietorship structured as a 2J entity, William Klesalek operates as a small, agile firm based in Mandan, North Dakota, with a regional footprint focused on federal installations in the Northern Plains. While no formal government certifications are held, the contractor’s consistent delivery of specialized repair work demonstrates reliability and technical competence in a highly specific segment of the federal contracting market.
